ET times
 

hey guys, just got a chance to run my 96 cobra.. all stock cept for BBK h-pipe no cats, an filter.

i went a best of 14.0 @ 101 with a 2.19 60ft.

not bad i tihink considerin no gear yet..

Not bad, now throw some 4.10s in it and drop that 60ft time down and your results will be much better.I had 3.73s in my 98 cobra, regretted it everyday that I didn't go 4.10s which is what I have now.:)

Re: ET times
 

since you have the cobra I would go with 4.10s for power adder and 4.56 for n/a

I think you can get those times down in the 13.5 range my GT ran a 14.1@98 with 2.1 60' stock down to the filter your mph is showing you have more power then your ET shows

ya i wasnt hookin up for nuttin ... i spun 1st, 2nd pretty bad.. so i just need a gear an some tire.

Does anyone know what would come stock in and 04 M5 GT. And about how many rpms do they run with 3.73 @ 70 and 4.10 @ 70

M5?Are you abbreviating for a manual transmission(3650)?A stock GT comes out with 3.27 gears.
4.10s @ 70 is about 26-2700 rpms, 3.73s I'm guessing are about 200 rpms below that.

By the way, definitely go 4.10s.I love mine, and I'm guessing you are thinking of gas mileage since you want hwy rpms.I still get an avg of 23-24 on the hwy.

Yes I was referring to a 5 speed manual. And thanks for the info, I was wondering about the 410 or 373; if yall have had such good luck with 410 and still good gas mileage; why not right!!

I love my 4.10s, if you get anything else, you will probably regret it the second you drive one with them.

I went with 3.73's in my 03 gt, and shortly thereafter I wish I went with the 4.10's! Would it be worth the money to swap the 3.73s for the 4.10's??

Probably not, just sort of a "lesson learned".Take the money and get a plenum and TB, or some other part to improve hp.
